[a] x = 175 - 7.5p

For a, we are isolating the x variable to one side of the equation.

0.4x + 3p = 70

0.4x = - 3p + 70

x = - 7.5p + 175

[b] x = 115

For b, we are solving for x when p = 8.

x = - 7.5p + 175

x = - 7.5(8) + 175

x = 115

Answer:

- $\frac{27}{7}$

Step-by-step explanation:

Given

f(x) = $\frac{3}{x+2}$ - $\sqrt{x-3}$

Evaluate f(19) by substituting x = 19 into f(x)

f(19) = $\frac{3}{19+2}$ - $\sqrt{19-3}$

= $\frac{3}{21}$ - $\sqrt{16}$

= $\frac{1}{7}$ - 4

= $\frac{1}{7}$ - $\frac{28}{7}$ = - $\frac{27}{7}$
